Document Type and Number:
WIPO Patent Application WO/2023/236177
Kind Code:
A1
Abstract:
An eyepiece optical system and a head-mounted display device. The system comprises a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), and a sixth lens (L6) which are coaxially arranged in sequence along the optical axis direction from a human eye observation side to a micro image display device (I), and a certain focal length relationship is satisfied; the first lens (L1), the third lens (L3), and the fourth lens (L4) are positive lenses, the second lens (L2) and the fifth lens (L5) are negative lenses, and material properties of the lenses satisfy a certain relationship. The defects of the prior art are effectively overcome, the aberration correction capability is better, the processability is better, and performance indexes such as large field of view, low distortion, and high optical resolution are realized, such that the manufacturing difficulty, the manufacturing cost, and the product weight of the eyepiece optical system are reduced, the optical performance of the system and the user experience of the product are greatly improved, and the eyepiece optical system is suitable for the head-mounted display device and similar devices.
